摘要
对一座大跨度叠合梁斜拉桥在采取不同施工方案时产生的主梁内力进行计算分析,得出混凝土现浇湿接缝的最佳浇筑时间,同时对双节段循环施工的可行性进行了研究,达到了节约工期的效果。
This paper calculates and analyses the internal force of the main girder of a long-span cable-stayed bridge with composite beams when different construction schemes are adopted, and obtains the optimum pouring time of concrete wet joint in situ. At the same time, the feasibility of double-section cyclic construction is studied, which achieves the effect of saving construction period.
